Not really.!! Belt drive is far more accurate than R&P unless high quality precision ground which is expensive so defeats the point when building a cheap machine.

But yes for 5K I wouldn't expect or want either.!! . . . I actually suspected the original Ebay machine used R&P on the Y axis has I couldn't see any signs of motors or screws but now I'm thinking it may use belt drive but again either isn't good enough at 5K.!
